Switzerland's Archroma Launches Food-compliant Cartasol Yellow 6GFC Liquid Dye

Archroma has extended its Cartasol® range by introducing a new, improved bright yellow dye called Cartasol® Yellow 6GFC liq. that has no added diethanolamine (DEA) or triethanolamine (TEA, and also called TAN).

New European regulations have come into force that greatly lower the limits for DEA and TEA contents in paper and board intended for food-contact applications. Dye makers have used those auxiliaries in the past to help maintain storage stability and prevent deposits forming over time. However, these amines are under scrutiny as they are potentially mutagenic, meaning they may lose their ISEGA certificates, and no longer be considered suitable for food-contact applications." (Germany’s ISEGA GmbH provides independent testing and certification for food-contact and other materials.)

Archroma’s new, food-compliant yellow formulation is butyldiglycol free, and will completely replace its existing Cartasol® Yellow 6GFN liquid product by the end of this calendar year.

In 2015 the company began introducing a new palette of food contact grades that will help tissue paper makers create the exciting colors that the consumers desire. Since then it has rolled out the following new grades in the range:

• Cartasol® Blue GDFC liq
• Cartasol® Yellow 2GFC liq
• Cartasol® Red 7BFC liq
• Cartasol® Blue 3RFC liq

"At the time," Simon Boyd, Archroma’s head of global product management, colorants, packaging & paper specialties business, said: "We were already able to cover most color needs for food-contact applications with our existing dyes. Now by developing additional ones to extend our range we can fully meet our customers’ requirements."

The company’s continuing active dye-reformulation program has led to the latest launch of Cartasol® Yellow 6GFC liq. The new dye has been designed to have the same strength, shade and properties as its predecessor, but with the added advantage of being fully compliant with the food contact requirements. In addition, the new grades are REACH-compliant and fulfill the requirements of most major eco labels.

"Importantly, the bright greenish yellow color of Cartasol® Yellow 6GFC liq. is attractive and adds a vibrant new color option to those producing bright yellow and green tissue and related packaging, thereby further supporting design creativity", Boyd added.
